| Abstract: | The process flow of cold area in ethylene plant is complex and difficult,and it is the key to the process design of the whole plant.Taking the revamping of a 200 kt/a ethylene plant,the revamping of a 1100 kt/a ethylene plant and the revamping of a 1190 kt/a ethylene plant as examples,the technological characteristics of the revamping of cold area in sequential recovery process is emphatically discussed.The process revamping schemes of cryogenic and demethanization system,refrigeration system and C 2 recovery system are discussed,and the process technological characteristics the specific revamping scheme of each plant are analyzed.The best revamping schemes and revamping principles of sequential process cryogenic system,refrigeration system and the whole ethylene plant are summarized. |
